CENTRIFUGAL PURIFIER.

Original application filed February 5, 1924, Serial 110. 690.861.

Dividedv and this application filed March 3, 1325. Serial No. 2.893.

This apparatus is 'a division of my original apparatus S. N. 690,861, filed February 5, 1924.

This invention relates to means for the centrifugal treatment of various fluids without resort to rotating parts. It is adapted for employment in drying, cleaning and purifying many liquids, gases and vapors but as a leading use in the purification of steam issuing from boilers, drums, and casings, it will herein be exemplified in a form and arrangement suitable to such use.

k The invention will be readily understood on reference to the drawings thatform part of this specification; in which, Fig. 1 is a vertical cross section of a steam boiler drum equipped with'a steam purifier embodying this invention. Fig. 2 is a vertical section illustrating the steam purifier in slightly modified form; and, Fig. 3- is a horizontal section on the line 33 of Fig. 1.

The drying or cleaning of steam at the outlets of steam boilers has hitherto presented problems of such difiiculty as to be solved, if at all, only by resort to extensive and expensive apparatus of relatively great size. The whole problem is here solved by the mere combination of the disclosed centrifugal unit with such steam outlet and thereby all globules of moisture and all particles of solid matter entrained in the steam may be successfully and reliabl separated and thrown back into the boi er, leaving only the rectified or purified steam to pass out through the boiler nozzles in truly dried condition.

In Fig. 1 the novelcentrifugal unit 358, in a simplified form, is shown in the steam space 359 and at the steam outlet or nozzle 360 of thedrum 361 of a steam boiler. The other components of the boiler are omitted for sake of clearness. The centrifu a1 unit comprises the centrifugal tuyere ring 362 best shown in Figs. 1 and 3, clamped between the top plate 363 and the bottom plate 364 by means of the bolts 365, which in this case also serve to suspend the unit from the top of the drum 361. In the plate 363 is a central outlet, marking the annular abutment, 366, and containing the outlet nipple 367. The latter may have a tapered end which is thrust into the base of the nozzle 360 to make a comparatively tight joint therewith. The floor 364' of the bottom preferably rises slightly above the lower lands (2 of the staves composing the tangential tuyere ring 362, thus to leave a free passage for the expulsion of the collected water, as about to be explained. .As clearly shown the raised part of the plate provides an annular centering shoulder and seat for the lower end of the tu'yere ring.

It will be understood that, as is always the case, a pipe leads from the nozzle 360 to a suitable steam valve 01' throttle, and thence to the engine or other point of the use'of the steam. The steam issues from the boiler under pressure and with a velocity of several thousand feet per minute. As the tangential tuyeres, e, are constantly open, all

parts of the unit are balanced as to pressure;

and it is because of this that the seemingly small and frail elements of these units are indefinitely durable. They are never subjected to severe strains, nor to unevenness of expansion and contraction.

Attention is called to the modified form of unit-bottom shown at 368 in Fig. 2. There the external annular rib 369 serves to hold the bottom of the tuyere ring, and the water which is collected is discharged through several holes 370 in the bottom plate. These arevclose to thebase periphery of the tuyere ring in order that the centrifugal thrust of the water may prevail to expel the water. p

The steam entering the tuyere ring is of course caused to whirl therein with great rapidity. Due to the filmization of the steam in the slit like tuyeres- 6 every particle of moisture is first positioned close to and then hurled against the inner faces of the obstructing staves of the ring. Thus the definite separation is accomplished. Though held against the staves by centrifugal force, the collected water and solids finally sink (by gravity) upon the bottom. Unable to find other escape, the water, under the continuing centrifugal force, is either thrust back into the steam space from between the feet of the staves as in Fig. 1) or downthrough the holes 3 0 (as in Fi 2). The dried steam, reacting against t e bottom, finds a free ath of escape upward along the axis of tii et360,

e unit and through the out- 5 Having thus described my invention 1 claim as new and desire to secure by Letters Patent 1. A fluid container having a fluid outlet in its to in combination with a horizontal member aving a central outlet, means conmeeting said outlets, a depending ring concentric with said member but of a larger diameter, leaving an annular abutment portion which presents its edge to said ring, said ring containing a circumferential series of o eratively overlappinginwardly directed slitike tangential tuyere which extend downward from said abutment, and a member closin the lower end of said 'ring approximate y in the plane of the lower ends of said tuyeres and constructed and arranged to permit the discharge of the heavier substances at its periphery and downward into said container.

2. A fluid container having a fluid outlet in its top, in combination with a horizontal member having a central outlet, means connecting said outlets, a depending ring concentric with said member but of a larger diameter, leavingan annular abutment portion which presents its edge to said ring, said ring containing a circumferential series of operatively overlapping inwardly directed slitlike tangential tuyeres which extend downward from said abutment, and a substantially flat member closing the lower end of said ring approximately in the plane of the lower ends of said tuyeres and constructed and arranged to permit the discharge of the heavier. substances at its periphery and downward into said container.

3. A fluid container having a fluid outlet in its to in combination with a horizontal member aving a central outlet, means connecting said outlets, a depending ring concentric with said member but of a larger diameter, leaving an annular abutment porneiaese tion which presents its edge to said ring, said ring containing a circumferential series of operatively overla ing inwardly directed slit-like tangential tuyres extending downward from said abutment, and, a me ber closing the lower end of said ring and therewith providing a plurality of openings for the discharge of the heavier substances removed from the fluid,

5. The herein described improvement for the centrifugal treatment of fluids without resort to rotating parts, comprising an upright ring containing a circumferential series of longitudinal inwardly directed and operatively overlapping slit-like tangential tuyeres; in combination with an upper endclosure containing a central outlet for the purified fluid and presenting an annular inner surface edgewise to said tuyeres and perpendicular to the axis of said ring, a closure for the lower end of said ring substantially opposite the lower ends of said tuyeres and therewith presenting a plurality of openings for the discharge of the heavier constituents of the fluid at the periphery of said ring.

In testimony whereof I have hereunto set my hand this 26 day of February. 1925.
